Async communication is the practice of sharing information and making decisions without requiring real-time interaction. Written-first culture, video updates via Loom, threaded discussions, RFC documents, and decision logs replace synchronous meetings. Core practices: full-context messages, documented decisions, clear response-time expectations, and knowing when sync is actually needed. 4-6 months of practice moves from 'meeting default' to 'async-first mindset.'

What is Async Communication

Async communication is the practice of sharing information and making decisions without requiring real-time interaction. In distributed teams across time zones, async-first communication enables productivity, reduces meeting fatigue, and creates better documentation as a byproduct. Mastering async communication means writing clear messages with full context, making decisions transparently in shared documents, and knowing when synchronous communication is actually needed.

❓ FAQ

What's the difference between async and just waiting for a response?
Async communication is intentional design: you craft messages with full context upfront, not expecting the recipient to be available now. You set clear response-time expectations (72 hours vs. same-day vs. FYI). Waiting is passive — you send a Slack and hope they see it. Async is active — you write as if this message is the only thing they'll see about this topic, include background, decision history, and next steps.
When does async fail?
Time-sensitive crises (production down), high-context brainstorms (whiteboarding ideation), or emotional conversations. If the answer requires back-and-forth 10 times in 30 mins, sync is faster. If someone is visibly upset, a 5-min video call beats 10 written rounds. Rule: async for decisions, implementation, updates; sync for emergencies, complex creative work, and conflict resolution.
How do I write an RFC (Request for Comments)?
Structure: Problem (2 para) → Proposed Solution → Alternatives Considered → Implementation Plan (timeline, risks) → Open Questions. Post in a shared doc, tag stakeholders, set feedback deadline (48h-1 week depending on impact). Treat it as a written design doc. Bad: 'Should we do X?' Good: 'We have 300 enterprise requests pending features Z and K. Proposal: timeline-prioritize K first (3 weeks, 2 eng, reduces churn by ~5%).' Attach data.
What's the etiquette for Loom videos?
Script your key points, keep <5min, include timestamps (00:00 — overview, 01:30 — code walkthrough, 03:45 — decision point), add captions for accessibility. Use zoom 125% so viewers can actually read code. Stop talking every 30s (silence feels long but buys thinking time). Post a TL;DR bullet list below the embed. Treat it as a replacement for a meeting, not a bonus.
What are ADRs and why do they matter?
Architecture Decision Records: one-page docs for each technical decision (why we chose PostgreSQL over MongoDB, why we split auth into separate service). Date it, list alternatives, explain trade-offs, link to RFC or issue. Build a living docs library so future engineers don't re-litigate the same decisions. Good async culture defaults decisions to text first.
Should everything be public by default?
Yes for technical decisions, processes, design docs, roadmaps — forces clarity and enables anyone to catch errors. Private is fine for: salary data, personal feedback, personnel matters, executive strategy pre-announcement. Rule of thumb: if a new team member should eventually know it, post it public. If it's confidential by nature, lock it down and archive after it's no longer sensitive.
How do I handle time-zone async?
Accept there's no same-day turnaround across 8+ zones. Set expectations: decisions turnaround in 24-48h, not 4h. Record meetings, post key decisions in Slack with video link. Use a status board (Notion) where each timezone updates their progress end-of-shift. Schedule one annual/quarterly sync on each side's evening; async handles everything else. This actually scales better than everyone pretending 'early morning' meetings work.
